cif/Reconstructing spacegroup designators from the symmetry operators werepossible. The comands used can be found in the log filereformat-spacegroups-2009.11.14.log committed with the currentrevision. Only lines that contained spacegroup designators werechanged, and all files pass vcif test after the conversion.
